Thanks so much Bart,
That's the case..... because vm running on cluster is more similar to
VMware HA solution (only two hosts without front-end)....
For the glusterfs i've already used this solution on my public cloud
with success.
You helped me for port-setup of hypervisors :)
I hope (like you) that someone (users or OpenNebula Team) have best
practices on how to run OpenNebula in a VM.
Thks.
